Participating Delta Dental Dentist Uniform Requirements

A Participating Dentist may not balance bill any amount over the Maximum Plan Allowance listed on the Explanation of Benefits issued to a Participating Dentist and the Delta Dental Subscriber under any Delta Dental Plan for covered services. B. Payments to Non-Participating Dentists: When dental services are provided to a Subscriber by a Non-Participating Dentist, reimbursement for the service is made on the basis of the fee listed on the claim form or Delta Dental’s Non-Participating table of allowances, whichever is less. Payment for dental services rendered to a Subscriber by a Non-Participating Dentist is made directly to the Subscriber unless payment to the Non-Participating Dentist is required by law or contract. C. Pre-Treatment Estimate: Participating Dentists may submit a Pre-Treatment Estimate for any services prior to providing treatment, unless the time period between diagnosis and treatment precludes submission of a Pre-Treatment Estimate. D. Collection of Co-payments: A Participating Dentist shall charge and make reasonable effort to collect from Subscribers all Subscribers deductible and co-payment amounts. E. Discounts: If a Participating Dentist offers a discount to an eligible Subscriber, the fee submitted to Delta Dental should also reflect the discount. Co-payments made by Subscribers are not considered “discounts.” F. Down payments: A Participating Dentist can make financial arrangements prior to treatment with eligible Subscribers for approximate deductibles and/or co-payments. A Participating Dentist may not collect the anticipated Delta Dental reimbursement amount from the Subscribers. Following adjudication of the claim by Delta Dental, a Participating Dentist must reconcile with the Subscribers any amount due or refund owed. A Subscriber is not responsible for any amount in excess of the amount indicated under the “Patient Responsibility” column of the EOB payment form. G. Coordination of Benefits (“COB”): When a patient is covered by two or more group policies or dental programs or Plans (“coverage(s)”), the COB provision allows the patient to receive benefits for covered services from each carrier, not to exceed more than 100% of the total fee for a given treatment COB rules apply when two or more insurers cover the same person for the same or similar benefit. Delta Dental coordinates benefits for Subscribers by determining primary and secondary carrier coverage. The primary coverage pays benefits up to its limit, as it would in the absence of any other coverage. The secondary coverage pays the difference between the primary coverage benefits and the total incurred allowed expense up to the secondary coverage’s limit. When Delta Dental applies the COB provision, its reimbursement as the secondary coverage when added to the primary coverage payment will not exceed Delta Dental’s allowable charge. Credits to eligible Subscribers’ accounts, or any Delta Dental fee adjustment must be made following the coordination of both coverages. 5 DDNC ParProviderURs prrl 02/2014 Revised – April 2020

H. Finance Charges: A Participating Dentist shall not apply finance charges to Subscriber’s accounts. I. Fee Schedule and Reimbursement Changes: Any changes made by Delta Dental to the fee schedule or reimbursement will be communicated to Participating Dentists in writing in least thirty days (30 days) prior to their effective date. SECTION 3: CLAIM SUBMISSIONS A. General Requirements: All claims and Predeterminations for all dental services, including those exceeding the Subscriber’s annual maximum benefit, must be submitted to Delta Dental by a Participating Dentist for Subscribers on an American Dental Association (“ADA”) approved claim form using the current version of the ADA CDT procedure codes in effect on the date services are rendered. A Participating Dentist may not submit claims for payment of treatment for Subscribers until such procedures are completed. Charges for dental procedures requiring multiple treatment dates shall be considered incurred and shall be applied to the Subscriber’s maximum on the date the service is completed. All claims submitted must reflect the actual service completion date. Failure to submit the actual completion date is non-Compliance as defined in Section 10.A. A Participating Dentist agrees to submit a claim form for all services rendered to Subscribers for which a charge is made. A Participating Dentist may not submit, cause, or permit to be submitted to Delta Dental any claim form, electronic claims submission in any form, or any other statement which contains false or misrepresented information. False or misrepresented information includes, but is not limited to, services charged to the Subscriber that are not submitted to Delta Dental and misinformation concerning dates of service. The license number of the treating dentist must be included on the claim form. A Participating Dentist shall submit all coordination of benefits information on a claim form to Delta Dental and cooperate with Delta Dental so that the claim can be properly adjudicated. B. Participation in National Delta Dental Programs: A Participating Dentist in the Delta Dental Premier and Delta Dental PPO networks automatically participates with the corresponding national Delta Dental programs (“Delta Dental Premier”, and “Delta Dental PPO”). Claims for Subscribers eligible in these programs should be submitted to the Delta Dental control organization handling the group account under which the Delta Dental Subscriber is covered. Payment for Delta Dental of North Carolina Participating Dentists in the Delta Dental Premier, Delta Dental PPO, DeltaCare and all national programs is based on the Participating Dentist Delta Dental of North Carolina Maximum Plan Allowances and applicable national coverage processing policies. Participating Dentists are required to accept the approved fee for procedures provided for national Subscribers when reimbursement is not payable due to a deductible, annual maximum, waiting period or frequency limit. The Participating Dentist is not allowed to balance bill for any difference 6 DDNC ParProviderURs prrl 02/2014 Revised – April 2020

between the allowed fee and the submitted fee. This prohibition on balance billing does not apply to services denied as non-covered. C. Infection Control: Infection control is an integral part of a dental office’s general overhead. Infection Control may not be billed to Delta Dental or Subscribers as a separate procedure. If a separate charge for infection control procedures is submitted on a claim form to Delta Dental, it is not billable and the Participating Dentist may not collect this amount from the Subscriber. If collection is made from a member or this service is billed to Delta Dental under a non-descriptive code, the action constitutes non-Compliance. D. Validation of Subscriber Identity: Delta Dental will maintain, on its website, a system whereby a Participating Dentist may verify the eligibility of a Subscriber based on the most current information held by the Plan prior to the provision of services. A Participating Dentist should validate that each Delta Dental patient is a Subscriber or dependent by accessing Dental Office Toolkit or other selfservice tools, by comparing the Delta Dental identification card to a state issued form of identification, or by past history of treating the patient. If a Participating Dentist provides services to a person who is not an eligible Delta Dental Subscriber, the Delta Dental payment for services is subject to recovery. E. Notice to Subscribers of Dental Services Not Covered by Delta Dental: A Participating Dentist must notify a Subscriber about any personal financial obligations for non-covered health care services in accordance with billing permitted under Section 2(A). F. Timely Claims Submission: A Participating Dentist must submit claims for services within twelve (12) months after the service is completed. Failure to submit a claim within the time required does not invalidate or reduce any claim however, if it was not reasonably possible for the claimant to file the claim within that time, provided that the claim is submitted as soon as possible and in no event, except in the absence of legal capacity of the claimant, later than one year from the time the submittal of the claim is otherwise required. If Delta Dental denies a service or services on a claim due to late submission, the Participating Dentist shall not charge or bill the Subscriber for the amount that Delta Dental would have paid if the claim had been submitted in a timely fashion, provided that the Subscriber advises the Participating Dentist of Delta Dental coverage at the time of treatment. G. Deductions. A Participating Dentist authorizes Delta Dental to deduct from any payments due to Participating Dentist any amount determined to be properly due to Delta Dental as a refund of payments incorrectly made to or claimed by the Participating Dentist. Delta Dental will provide the Dentist with notice of the specific claim for which an overpayment amount was made and the basis 7 DDNC ParProviderURs prrl 02/2014 Revised – April 2020

on which Delta Dental believes that the payment made was in excess of the amount properly due under the affected dental Plan(s), and will request that the overpayment amount be returned to Delta Dental. Should the Dentist return the overpayment amount, Delta Dental’s right of recovery will have been satisfied. If the Dentist fails to return the overpayment amount within 30 days of the notice, Delta Dental reserves the right to offset the overpayment amount from any future payments due that Dentist for services covered by Delta Dental. Where overpayment amounts are recovered by means of an offset, the overpayment and offset amounts will be properly credited to, or debited from, the affected dental Plan(s) so that all involved dental Plans will have been administered according to their terms and will have paid only the amount that is properly payable for the services provided. The recovery of overpayments or offsetting of future payments shall be made within the two years after the date of the original claim payment unless the insurer has reasonable belief of fraud or other intentional misconduct. The recovery of underpayments or nonpayments shall be made within the two years after the date of the original claim adjudication. SECTION 4: CREDENTIALING & MAINTENANCE OF LICENSURE A. Each Participating Dentist must cooperate with and complete Delta Dental’s credentialing and recredentialing processes. B. Delta Dental’s credentialing documents will be provided to a Participating Dentist upon written request. C. At all times Participating Dentist must maintain professional liability insurance at Participating Dentist’s expense in an amount consistent with acceptable dental industry standards for injury to, or death of, one person in any year, or in amounts as required by state law, but in no case less than liability coverage of 500,000 per claim and 1,000,000 aggregate. Participating Dentist agrees to notify Delta Dental within ten (10) days if coverage is cancelled and to provide Delta Dental with evidence of coverage if requested. Participating Dentist agrees that Delta Dental may review malpractice claims filed against him or her. D. Participating Dentist must immediately inform Delta Dental about any changes relating to their professional credentials or any changes in their professional liability coverage. In addition, Participating Dentist agrees to notify Delta Dental within thirty (30) days of any business changes that might affect the processing of claims. This would include a change to the business name, business address, business phone number, tax identification number or Social Security number, the dentists within a group practice, and the effective date of the change. E. Each Participating Dentist agrees to comply with Delta Dental’s utilization management, credentialing, quality management and provider sanctions program. However, none of these 8 DDNC ParProviderURs prrl 02/2014 Revised – April 2020

programs shall interfere with the Participating Dentist’s professional or ethical responsibilities or with their ability to provide information and assistance to any patients. F. Participating Dentist agrees to comply with Delta Dental’s credentials verification program. G. Participating Dentist agrees to respond in a thorough and timely manner to Delta Dental communications. Unless the communication indicates otherwise, Delta Dental requires receipt of a Participating Dentist’s response within 90 calendar days of issuance. If the requested information is not received within 90 days, Delta Dental may adjust claims history as necessary, and information received after the adjustment is completed may not be accepted. This may result in Participating Dentist owing a refund to Delta Dental. SECTION 5: NON-COMPLIANCE WITH THE PARTICIPATION AGREEMENT AND DELTA DENTAL’S CREDENTIALING AND RE-CREDENTIALING PROCESSES A. When non-Compliance with the Participation Agreement or Delta Dental’s credentialing and recredentialing processes is identified, Delta Dental will examine all relevant documents and information, and conduct a complete investigation. B. If non-Compliance with initial credentialing is verified, the Dentist applying for Participation will be notified in writing of the facts and Delta Dental’s requested corrective action. C. If non-Compliance with the Participation Agreement or recredentialing is verified, the Participating Dentist will be notified in writing of the facts and Delta Dental’s requested corrective action before Termination except in the case of Immediate Termination. D. The failure to correct any credentialing deficiencies, the receipt by Delta Dental of additional adverse findings, or the failure to disclose any requested information may result in further corrective action or Termination of a non-compliant Participating Dentist. E. Examples of non-Compliance which could result in Termination, or Immediate Termination include but are not limited to: Any suspension or termination of a Participating Dentist’s license by a State Board of Dentistry or licensing authority that renders a Dentist unable to satisfactorily treat Delta Dental patients in the sole judgment of Delta Dental.

However, the dentist’s participating status shall be revoked as of the date indicated in the notice of Termination.

Quality assurance processes include, but are not limited to, utilization review, credentialing and recredentialing, 10 DDNC ParProviderURs prrl 02/2014 Revised – April 2020

and quality assurance audits. Participating Dentist also agrees to cooperate fully with any state or local dental society peer review committee and/or consultant designated by Delta Dental to review dental services, including quality of care, provided by the Participating Dentist to a Subscriber. The decision of any consultant or committee, subject to any applicable appeals process, shall be binding on the Participating Dentist and Delta Dental.
